Moderate disturbances may boost biodiversity but also increase the risk of invasive species
In short: A review of ecosystem dynamics found that while moderate levels of disturbance can promote high species diversity, these same conditions often make environments more vulnerable to being overtaken by invasive species. The research highlights a complex balancing act for conservationists who must manage natural cycles like fire and grazing.
The study examines the "intermediate disturbance hypothesis," which suggests that biodiversity peaks when disturbances are neither too frequent nor too rare. However, because many human-driven changes—such as soil disturbance or nutrient addition—alter these patterns, they can inadvertently open the door for non-native species to dominate.
This review synthesizes existing knowledge on various disturbance types in grassland vegetation. A key limitation is that it focuses on general ecological principles and interactions rather than providing new primary data from a specific field site.
Why it matters: Conservationists must carefully balance disturbance levels to protect native biodiversity while preventing invasive species from taking over.
